That is what I have found. Every vehicle we have purchased since 1996 we went in ready to pay in cash or check, whichever got the best deal, and ended up financing for one reason or another. The wifes last 3 cars we got with 0% financing and various incentives (in each case we worked out the out the door price before discussing interest rates). The 2018 Raptor we got 0 down and 1.9% financing, they would not do 0% on that thing.
I always put the cash back into an investment, intending to "use their money". But I got to tell you, in every case I eventually get tired of seeing the bills come in and pay the thing off anyway, the loans seldom last as long as 18 months. The Raptor payments lasted 7 months, the most recent Lincoln payment 1 month, the first bill that came in on that I just wrote a check for the 10 day payoff amount. I know in my head that leaving the money in an investment is the smarter thing, but getting bills in the mail sucks. My wife tries to never let me see the bills for that very reason. We pay every necessary bill that we can (trash, water, etc) at the beginning of the year just so I don't have to see the mail in the mail box
T!
